JOHN WALDHEIM, 0F ELIZABETH, NEW JERSEY, ASSIGNOR TO UNDERWOOD COM- PUTING MACHINE COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.

To all whom it may concern:

Be it known that I, JOHN'X/VALDIHEIM', a citizen of the United States, residing in Elizabeth, in the county ofUnion and State of New Jersey, have invented'certain new and useful Improvements in Combined" Typewriting and Computing Machines, of which the following is a specification.

This invention is illustrated as applied to a combined typewriting and computing machine which may be like-that shown in the application of Henry L; Pitman, No. 198,375, filed October 25, 1917 (now Patent No.1,- 350,387, dated August 24, 1920), in which a sub-carriage or cross-computer carriage is adapted to travel intermittently"with the typewriter carriage during the letter-feeding movements of the latter. In other words, the computer-carriage is picked up every time the carriage passes into a computing zone, and becomes released from the typewriter carriage as it passes out of the computing zone.

The typewriter carriageis sometimes re.

positioned in computing zone, for example when making corrections. When this is done under ordinary conditions, it is necessary to move the carriage back beyond the computing zone, in order to pick up the cross-computer carriage, andthen move the typewriter carriage forwardly to the de nominational positionin the computing zone.

In the Pitman; application above referred to, means is provided by which the crosscomputer'carriage may-be connected with the typewriter carriage by'means of a key in the beyboard after the typewriter carriage has beenmovedback into the computing zone.

. An object oi this invention is to provide means to'reconnect the cross-computer carriage or sub-carriage with the typewriter carriage by means actuated directly by the typewriter carriagewhen the latter is moved back intothe computing zone.

In carrying out the invention, pick-up devices, located in the columnar positions of the typewriter carriage, may engage to ao-. tuatea cam member. when the carriage is moved back; Thecam member-forms'part of a connection, which extends from' the cross eomputer carriage, and, when actuatedy is, effective to reconnect the computer" Specification of Letters Patent.

passed through a computing zone in a letterfeed direction.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1. is a rearview of the upper part of the machine. and shows the typewriter carriage and the cross-computer carriage I traveling through a computing zone.

Figure 2 is a similar view and shows the parts. in position .after the carriage has passed 'outof the computing zone with the cross-computer carriage returned to its nor mal position. I

Figure 3 is a viewsiinilar to Figure 2, and shows the parts in position when the typewriter carriage is backed into the com. puting zone, the cam member being actuated by the pick-up device and the pick-up hookreconnected with the pick-up device.

Figure 4: is a 'lraginentary sectionalside view. taken on the line 4-4 of Figure 1, and looking indthe direction of the arrows at said line.

Figure 5 isv a detail perspective view, as

pivoted lever with the shifter and the cam member carried thereby, and shows the shifter actuated by one of the pick-up de vices to move the cam member out of ef fective relation with the pick-up devices.

Figure 9 is a detail perspective view of the parts which constitute the shifter.

Numeral keys (not shown) swing typebars 10 upwardly and rearwardly to cause types 11 to strike against the front side of a platen 12 (Figure 6) rotatively supported on a carriage 13. The carriage is urged in a letter-feeding direction by a spring-drum 14: (Figure 1) connected to said carriage by a strap 15. The lettertfeeding movements of the carriage may be controlled by escape ment devices (not shown), which may be like those used in the Underwood machine.

The carriage may be rapidly positioned denominationally in any one of a plurality of columns by key-actuated denominational stops 16 (Figures l and 6), which are adapted to release the carriage and engage with column-stops 17 to arrest the carriage in the proper position.

The numeral keys are adapted to actuate a master wheel 18 through various distances, the extent of rotation being proportional to the values of the numeral keys. Column-totalizers 20 are adjustably supported on a bar 21 mounted to travel on a fixed rail or guide bar 22 and with the carriage, so that, as the carriage passes through a computing zone, computing wheels 23 are brought seriatim into effective relation with the master wheel. 18. The column-totalizers 20 may be adjusted in positions corresponding with the positions of the column-stops 17, so that any one of them may be rapidly positioned relatively to the master wheel by the denominational stops 16.

A cross-totalizer 2 1- is provided so that computation may be had crosswise of the various columns. The cross-totalizer is adapted to travel intermittently with the carriage (in a manner which. will be pres ently described) to bring computing wheels 25 seriatim into effective relation with a master wheel 26. The master wheel 26, for the cross-totalizer 24:, may be connected with the master wheel 18 for the column-totalizers, so as to rotate in unison therewith. For this purpose,the master wheel 18 is connected with a horizontal shaft 27, which drives a vertical shaft 28 through a pair of bevel gears 30 and 31. The vertical shaft 28 in turn drives a horizontal shaft 32 through bevel gears 83 and 34, the horizontal. shaft being connected with the master wheel 20. The cross-totalizer is supported on a traveling bar or cross-computer carriage 35 guided on a fixed rail or guide bar 36.

To cause the cross-totalizer 24 to travel intermittently with the typewriter carriage 13, there is set at each column-stop 17 a pickup element u. As the carriage enters the computing zone, the nearest pick-up element engages with a hook 38 on a piclcup bar 39 pivotally connected at 10 to a rack 11, to move the latter rightwardly (Figure 1). The rack actuates a double sector member 412 to rotate the pinion 4:3 secured to a shaft tt extending from the back: to the front of the machine (Figure 6), where it is provided with another pinion d5 engaging with a rack 4L6 on the cross-computer carriage to move the latter step by step relatively to the master wheel 26 as the numbers are typed while the carriage 18 is in the computing zone. As the carriage passes out of the computing zone, the pick-up bar becomes released from the pick-up element by a pin 4:? on the pick up bar 39, which enga es a cam L8, on a fixed plate 50. The picleup bar is swung about its pivot 4-0, thus freeing the hook 238 of the pick-up element and permitting the pick-up bar 35) to be restored to its normal position (Figure 2) by a return spring 51 coiled about the shaft t l, which connects the double sector member 42 with the rack 46 on the cross computer carriage. Thus, the spring 51 also returns the cross-totalizer 24k to its normal position at the right of the master wheel 26. The hook 38 on the pickup bar may he held in the path of the pickup elements 3? by a spring-controlled lever, 52, l'iavingz a stud 53 thereon bearing againstthe under side of the pick-up bar 39.

The columnstops 1.7 and the pickup ele ments 3?, of which there may be one of each for each letter-space position, may be sel.ec tively set by a key in the keyboard, as in the Pitman application above referred to, and may he held in their ineffective and effective positions by detcnts 5 1 and 55.

To reposition the eross-totalizer relatively to the master wheel and reconnect it with the typewriter carriage when the latter is moved back into the computing zone, the piclcup elements 37 are adapted to engage a cam 56 (Figure 2) on a cam member 57,

to more the latter upwardly to swing a lcver 58 about its pivot 59, to pull. upwardly link on which is connected at its lower end to an arm 61 extending from a shaft (32, so that the latter may be rocked thereby. The shaft 62 has extending forwardly therefrom another arm 63. which pulls dmvmvai'dly on a link 64, to rock a bellcrank 65 Rl'FOllfits pivot 66 to reposition the eross-totalizer 534i: relatively to the master wheel 26, by pulling it leftwardly (Figure 6) by a connecting link 67. While the cross-totalizcr is being repositioned, the pick-up bar 2-39 is also advanced toward the pick-up element to reconnect it therewith, while the pick-up element on the carriage is being moved back into the computing zone. This advancin movement of the pick-up bar '39 is effected tln'ough the connection, hereinmembers 37.

before described, including the horizontalshaft 44 extending rearwardly from the rack bar 46 on the cross-compu er carriageor subcarriage 35. i

The cam member 57 is pivotally mounted on a pin (38 on the lever 58 and is provided with another cam at its lower end (Figures 5 and 7) so that it may be swung to one side by the various pick-up elements as they pass itwhen the carriage moves in .a letterfeed direction. ll. leaf sprin -g 71 is provided to return the cam member 57 to its normal effective position each time a pick-upelementhas passed it. It should be understood that the detents 55 are strong enough to prevent displacement of the piclnup elements by the leaf spring 71. The pick-up elements 37 are beveled at 69 l'Egures 5 and 7) to facilitate their engagementiwith the cam 70 on the cam member 57 i I i It is desirable to render the cam member 57 inefl ective, so as to avoid unnecessary reelprocations of the cross-totahzer 2 asthe tuatinp; member 74 to rock the arm 73 about ltS pivot through the mediums of? a pin 77 with which the arm engages. Theupper end of the arm 78 is provided with a stud 78 engaging}; in a cam slot 80 of an intermediate lever 81 to swingthe latter about its pivot 82 and cause its opposite end to move upwardly to move the cam member 5'? therewith to withdraw it from effective relation with the pick-up members 37 (Figure 8) the cam member 5? being; connected with the intermediatelever by a pin 83 pro jecting into a slot tormed in the lever 81.

has the carriage continues to move backwardly the pick-up members 87 engage with the operating member which, in the meantime has been moved into efl'ective relation with the pickup members (Figure er and swings the operating member idly about its pivot'and against the tension of a. sprino; 85 (Figures 1 and9) connected between the two actuating members 741- and 75, which normally holds said members against the stud 77 on the arm 73, l Vhen the carriaa'e is again advanced in a letter-feeding direction (rightwairlly in Figure 8) the nearest pick-up memberh? engages with the actuatiirgmember 75 to swing; the shifter 72 about the stud 76 and actuate the intermediate lever 81 to lower the cam member 57 into eftective relation withthe pick-up This occurs prior to the en.-

scope of the invention, and'portions oi the improvements may be used without others.
